The goal of this project is to improve the design of current capacitive micromachined ultrasound transducers (cMUTs) for the measurement of wind velocity in a Martian environment, which is mainly composed of carbon dioxide with an atmospheric pressure less than one percent that of Earth’s mean sea level pressure. With the aid of Critical Point Drying, a smaller operating frequency can be achieved ... read morefor better signal detection (<100kHz). Other processes such as Nickel plating are also being modified to increase the yield of working devices. Submitted in partial fulfillment of the grant requirement of the Tufts Summer Scholars Program. read less
